CAHOKIA, Ill. – A Metro East teenager is facing a dozen charges for making threats against two school districts.

The state’s attorney said the 14-year-old girl posted the threat on Facebook against Cahokia High School and East St. Louis Senior High School.

“I will be shooting at Cahokia tomorrow morning this is no joke then coming to Eastside!!! [sic]” a screenshot of the threat shows.

The post forced the Cahokia and East St. Louis school districts to increase security and even put some schools on a soft lockdown Thursday.

The girl is now charged as a juvenile with four counts of making a terroristic threat, four counts attempting to make a terroristic threat and four counts of disorderly conduct

“We cannot assume anything is a joke. We cannot ignore any type of threat. We have to act, and if you take those initial steps and you take them seriously, you’re going to be able to prevent some very, very dangerous things from happening, and you're going to prevent people from getting hurt,” St. Clair County State’s Attorney Brendan Kelly said.

The teenage suspect is being held in a juvenile detention center. A hearing is expected in the case Monday, and the state’s attorney said his first step will be asking the judge for this girl to receive a mental health evaluation.
